Description: WSDOT's Corridor Sketch Initiative is a set of planning activities that engages the agency's partners to determine the context and performance of state highway corridors and identify high-level strategies for addressing performance gaps. The initiative complements and supports regional planning processes around the state and serves as the foundation for practical solutions and integrated scoping. WSDOT uses the results of the Corridor Sketch Initiative to determine where the agency should do more in depth planning and analysis. For more information on the Corridor Sketch Initiative, go to https://wsdot.wa.gov/engineering-standards/planning-guidance/planning-study-guidance/corridor-sketch-initiative. WSDOT divided the state's highway system into 304 functional segments that serve communities, economic regions and regional networks. The agency considered traffic characteristics, Freight and Goods Transportation System classification, access management, roadway characteristics, seasonal closures, land use, and proximity to intermodal centers such as ports or transit centers.
